Before trying this you should read the introduction to Virtual Colossus.
This scenario is an intercept of 5668 characters accessed in
Virtual Colossus as "BR2cipher" and "BRpatterns". It needs the K2 one-back
First use the 1+2=. algorithm to set X1 and X2.
You may find that there are more than one large count.
Then use 4=5=/1=2 to set X4 and X5. Also use this to eliminate
wrong high counts in K1, K2.
Now use count of "///" to set X3 given X1,X2,X4 and X5.
This will also eliminate contending counts.
Still with DeltaZ and DeltaX added onto the Q bus, count "///"
with the count limitation switch down to set M1 and M2.
With them set, switch direct Z, X and S to the Q bus.
Set S1 and S2 with 1+2=. then S4 and S5 with 1+2=. finally set
S3 with 3=+
With all wheels set, by using "T" (trace), Q should show the decrypt.
Read the introduction to Virtual Tunny, then after selecting the cipher,
BR2cipher and the patterns, BRpatterns, set in the wheel start positions
you have just found and decipher the cipher text.
